19 # This harness is for testing builtin support. Each test has two files:
21 # - foo.c defines the main testing function, main_test().
22 # - foo-lib.c implements the library functions that foo.c is testing.
24 # The functions in foo-lib.c will often want to abort on certain inputs.
25 # They can use the global variable inside_main to see whether they are
26 # being called from the test program or part of the common runtime.
28 # In many cases, the library functions will behave as normal at -O0
29 # and abort when optimisation is enabled. Such implementations should
30 # go into the lib/ directory so that they can be included by any test
31 # that needs them. They shouldn't call any external functions in case
32 # those functions were overridden too.
